Culverton Smith: What's the very worst thing you can do to your very best friends?
Faith: Well? What is the worst thing you could do
Culverton Smith: Tell them your darkest secret. Because, if you tell them, and they decide they rather not know, you can't take it back, you can't unsay it. Once you've opened your heart, you can't close it again.
